Those stylish flash tattoos could do more than just look cool in the future. A team from MIT and Microsoft Research has developed a fabrication process called “DuoSkin,” which can be used to make temporary metallic tattoos that double as on-skin interfaces. MIT Media Lab already demonstrated their capability in three different ways. First, they can be used for input to control mobile devices and computers, transforming your skin into a trackpad, a button or a slider. They can also be used to turn your skin into a display of sorts, changing colors based on your body temp. Finally, they can store data that phones and other NFC-enabled devices can read.
